[LLVMdev] Sparc back end fix
Hi Tim, Thanks for the patch. I had a few questions though - just to make sure that I get the problem correctly. Currently, here is your flow, as I understand it : x86 llvm-gcc binary llc -march=sparc gcc cross/sparc source ---------------------> .bc ------------------> .s -----------------> sparc executable. Is this correct? Or did you manage to build the

[LLVMdev] Sparc back end problem
Hi everyone, I'm trying to make a cross-compiler based on llvm to target sparc (solaris) from x86_64 (linux). I couldn't compile llvm-gcc on my system so have to use the precompiled binaries from the website, but already have a gcc cross-compiler so can use this. So far, my compilation steps are these: 1) Preprocess the (C) sources using gcc cross-compiler 2) Use llvm-gcc to

Intel MPX support (instrumentation pass similar to gcc's Pointer Checker)
I've recently played with the GCC implementation of pointer checker on a real hardware, my recent impressions are here: https://github.com/google/sanitizers/wiki/AddressSanitizerIntelMemoryProtectionExtensions (there is also some old pre-hardware content). In short, I totally agree with what David says above: MPX is a disaster. (Usual disclaimer: my opinion here is too biased) I am glad

Intel MPX support (instrumentation pass similar to gcc's Pointer Checker)
Hello, even though the study of Intel MPX took much longer than expected, we have finally finished it. Currently, it is published in two formats: * as a technical report: https://arxiv.org/abs/1702.00719 * and as a webpage: https://intel-mpx.github.io/ This work contains evaluation of MPX from perspectives of performance (Phoenix, PARSEC, and SPEC benchmark suites), security (RIPE and found

[LLVMdev] Issue compiling llvm-gcc frontend on sparc
Hi all, I have successfully built LLVM itself, as all the tools (llc et al) are working fine. I built the latest release version (2.7). I have been trying to build the llvm-gcc frontend on a sparc machine. I encountered the following issues : 1) During configuration, the default assembler (installed at /usr/ccs/bin) is chosen to be used, but I want to use the GNU assembler (installed at

It's not *that* big. The patch is 634K uncompressed. I'd say it would be annoying to have that attached to an email message, but it's no bigger than existing MultiSource tests. --Patrick On 07/21/2010 08:13 PM, Daniel Dunbar wrote: > On Wed, Jul 21, 2010 at 11:57 AM, John Criswell<criswell at uiuc.edu> wrote: > >> Daniel Dunbar wrote: >>

Dmitrii, all, Please note, that GCC 5.3 had a significant update to the MPX code quality - please, use this version as reference.

[LLVMdev] Modifying the patterns/ instruction selection phase in LLVM 2.7
Hello all, I am trying to modify the Sparc backend to do something for my team's project, to do the following. Whenever the backend encounters a call to one particular type of function names (functions like p0(), p1()..etc), I want the backend to generate a "sethi %g0, <number>", and NOT a "call p0, call p1..." instruction. However, the backend should work as usual

Opening a web browser from R?
Hi, I was wondering if there's a way in R to open a web browser (such as Internet Explorer, or Firefox or whatever). I'm doing some analyses that have associated urls, and it would be nice to have the ability to directly open the relevant page from within R. I was looking at the help for 'url' and I can see I can probably access the information I need and display it in my

[LLVMdev] Modifying the patterns/ instruction selection phase in LLVM 2.7
I have similar requirements for my project. This is what I do. 1. Add a new intrinsic function to LLVM that corresponds to "functions with particular type of function names". The steps to create intrinsic function is documented in http://llvm.org/docs/ExtendingLLVM.html#intrinsic. 2. Create a lowering pass that lowers "functions with particular type" ( eg. p0, p1) to

[LLVMdev] Modifying the patterns/ instruction selection phase in LLVM 2.7
For my case, I can't replace these call instructions with inline assembly code because I need to encode the registers into the "number". For instance, if the call instruction is %result = call i32 @foo(i32 %a) and the result is assigned to register %l0 and the variable "a" to register %l1, then I encode all foo, %l0 and %l1 and generate a sethi instruction. thanks,
